Huawei Mate 20 Pro is one of the flagship mobile phones that is quite interesting in the second half of this year. Today, the well-known dismantling website iFixit brings the latest disassembly map. Let’s take a look at what can be seen inside this flagship mobile phone. . Mate 20 Pro has a 2K resolution AMOLED screen with a pixel density of 538 ppi. It is also equipped with off-screen fingerprints and 3D structured light, and is also equipped with the world's first 7-nanometer chip Kirin 980. The camera has inherited the previous Leica three lens, but removed the 20 million pixel black and white lens, replaced by a super wide angle of 20 million pixels. The two lenses in the area are 40 million pixel wide-angle lens and 8 million pixel telephoto lens. Compared to the P20 Pro, the Mate 20 Pro uses a curved screen, and the 'Liu Hai' is longer because it is a component that puts down the 3D light. (Mate 10 and Mate 20 Pro in the picture) On the back, the Mate 20 Pro without fingerprint recognition is more complete. The glass on the back is not so smooth. Huawei has added a non-slip and anti-fingerprint coating so that the phone does not slip out of the pocket. The Mate 10 Pro's speaker hole position was changed to a SIM card and NM card tray in the Mate 20 Pro. We use a heat gun to heat the glue on the back of the Mate 20 Pro, which is convenient for subsequent disassembly. Since the back material is made of glass, it is necessary to pay attention to the force when disassembling, and the force is too large to break the glass back cover. Mate 20 Pro has redesigned the location of the fingerprint, so there is no need to worry about tearing the fragile flexible cable when removing the back cover. Finally, we opened the back cover of this phone. Unpacking the back cover, first saw one of the new features of the Mate 20 Pro: two-way wireless charging coil. The charging coil of Mate 20 Pro is both a transmitter and a receiver. Huawei hopes that users can use it to charge some wireless charging headsets or to charge wireless phones. However, the latter can only be used as an emergency. After removing the eight screws, we removed the middle frame assembly, which included the wireless charging coil, NFC antenna and LED two-tone flash. The first feeling of just touching the motherboard is that the motherboard does not have any cable connections, but a closer look reveals that there are nine flexible cables that hold it in place and an antenna cable. Like the P20 Pro, Mate 20 Pro insists on using a relatively small motherboard to make room for larger batteries. Since 3D face unlocking hardware and 3-in-1 rear camera take up more board space than usual, Huawei has to cut Some camera holes and slightly change the layout. After opening some connections, we managed to remove the motherboard and the rear camera. The Mate 20 Pro has three rear cameras: Top right: 40 MP, f/ 1.8, equivalent to a 27 mm wide-angle lens; Bottom right: 20 MP, f/ 2.2, 16 mm equivalent super wide-angle lens; Bottom left: 8 MP, f/ 2.4 , 80 mm equivalent telephoto lens, 5x optical zoom. As the camera is removed, the content on the motherboard gradually emerges, including Toshiba's 128GB flash memory, power management IC and various LTE band modules. On the back of the motherboard we can see the Kirin 980 processor, Wi-Fi chipset and other precision chips. We removed the familiar front camera and 3D facial recognition component. It seems to coincide with what Huawei showed at the conference. We do some analysis, red is the point projector, orange is the front lens, the right side are the rangefinder / distance sensor, floodlight, ambient light sensor, infrared camera. The purple part we did not guess is a flaw. We use tweezers to dig out a part of the back of the motherboard. This section is mainly used for small interconnects of power and volume buttons. Above we saw chips such as radio power receivers. At this point, Mate 20 Pro's 'brain' is completely dismantled. Next we turn our attention to the other end of the phone. The SIM card slot usually doesn't show any new tricks, but the tray is not the same. It supports a new memory card format called nano memory (NM). The NM card is a nano-sized SIM card memory (45% smaller than a normal SD card) and can provide a maximum reading speed of 95 MB / s. Huawei's own NM card solves the problem of mobile phone operation caused by low-quality SD card. Slow question. Like the P20 Pro, the USB-C charging port is mounted on a large flexible cable. This means that if the charging port fails, you only need to replace the main cable - not the more expensive one. Another similarity to the P series: There is no 3.5 mm headphone jack. In addition, we can see a SIM card reader mounted on a small board, planted near the coin vibrating motor. Next, we look at the line and look at the power source of the Mate 20 Pro. To our surprise, we found some orange pull tabs on the left side of the battery and a simple guide on how to remove the battery - we like it, just like a wizard. The battery weighs an unprecedented 16.04 Wh (4,200 mAh, 3.82 V). In terms of raw capacity, it almost beats all phones – including its predecessor (15.28 Wh), iPhone XS Max (12.08 Wh), and even the heavyweight Samsung Galaxy Note9. (15.4 Wh) Next we took out the secret weapon - the multi-headed gun, through which the IP68 adhesive on the display was fixed. Yes, the last secret we need to explore is Huawei's curved screen. We thought that the work ended here, I didn't expect there was something inside. That's right, this is the under-screen fingerprint module provided by Huiding Technology, which is hidden under the AMOLED screen. It is not capacitive fingerprint recognition, but optical fingerprint recognition, which should be very familiar to Chinese users. When the finger is put on, the screen illuminates the phone, and the sensor takes the opportunity to record the fingerprint information. Come to a recent photo to see. This time it is really the end of the battle, this is the family portrait of Mate 20 Pro.
